Returning to Castle MacPherson was definitely not FBI profiler Duncan Sutherland's choice. But when defense attorney Piper MacPherson is targeted by a serial killer, Duncan knows it's the only place she'll be safe. At least, safe from her stalker. There's no guarantee he'll be able to keep his hands off her .

Now though, she wants the real deal. And with a serial killer threatening her life, the best thing Duncan can do is provide Piper with full-body cover-day and night!
